No.  

But when you do `make install' it runs `make modules_install' for the
kernel, which regenerates everything in the /lib/modules/2.6.xx
directories.

Separate packaging of these small LSM modules is still a work in
progress.  There are no standard solutions yet, AFAICT.  

If you want to help, there are people on the debian-multimedia ML
actively trying to figure out how to do this.  I'll do what I can, but
I am not a Debian Developer, nor an expert on the Debian packaging
system.

So would I.

If you want to hack something yourself, I suspect that the simplest
approach will be to turn it into a kernel patch, which you would apply
using the existing PATCH_THE_KERNEL mechanism of make-kpkg.  If you do
that, please keep me posted on your results.

It seems that a kernel-patch version of this LSM is worth having.
I'll work on that when I find time.  It should be straightforward.
But, I've got too many other uncompleted tasks right now.  :-)

The Debian multimedia people want a binary distribution method.  That
will likely require a different solution.
